What OS image can I use for Docker Swarm in Magnum?
Hi, I'm looking to set up Docker Swarm using Openstack Magnum and I noticed the user guide for magnum lists only Fedora Atomic as supported. If I'm not mistaken though Atomic has been discontinued for a while now, so I'm wondering what you use for this use case. Can I use Fedora CoreOS instead, and if so are there any gotchas I should know as a first time Magnum user? Thanks in advance, Paolo
Hi Paolo, As far as I know, swarm clusters are unmaintained since 3 or 4 years. So it won't work as expected. Most of the magnum users are using kubernetes therefore its maintained. For kubernetes clusters you can use fedora CoreOS 32. It works perfectly fine. You can use below link for installation. https://www.server-world.info/en/note?os=Ubuntu_20.04&p=openstack_victoria4&f=10 Ammad On Wed, Aug 25, 2021 at 5:25 PM Paolo Celati <paolo@celati.com> wrote:

Hi Ammad, thanks for letting me know. I suspected this could be the case, so I'll probably look into using Kubernetes instead. Paolo On 25/08/2021 14:57, Ammad Syed wrote:

For kubernetes clusters you can use fedora CoreOS 32. It works perfectly fine. fedora 32 is no longer reciving any security or package updates as its EOL if you do base you deployment on fedora core os i would suggest using a more recent version. im not sure if will work with magnuma but i dont think we really should recommend using an unsupported OS for any new deployments.
keep im mind that fedroa support policy is 2 release +1 month for hte base os. that tipically means its only supported for 13 months fedora 32 becamue EOL on 2021-05-25 3 months ago ideally if you are using fedora core os you would start form the most recent release and subscipe to t the stabel update stream https://docs.fedoraproject.org/en-US/fedora-coreos/update-streams/ the cloud image can be retrived here https://getfedora.org/coreos/download?tab=cloud_operators&stream=stable and the general openstack instuction are found here https://docs.fedoraproject.org/en-US/fedora-coreos/provisioning-openstack/ thse are really not targeted at magnum but rater makeing fedora core os avaiabel for other vms however you likely should use those images if they are compatibale with magnum.

fwiw I have seen (test)k8s clusters deployed with magnum which ran fedora coreos 34 more or less fine (I'm currently only aware of one bug, but there may be more).

We worked around those by using a version that didn’t switch to cgroupsv2 but yeah, this is an issue. On Thu, Aug 26, 2021 at 4:08 AM Ammad Syed <syedammad83@gmail.com> wrote:
